Modifying the foot pin to accept the compartment, the spacing device is used to protect the device; to maintain a pair of pin blocks

The pitch fixing hook frame 14 1 is detachably coupled by using a bolt ν

The width is separated from each other. Therefore, the distance between the pair of opening pins 1 2 构成 formed by the two pairs of the needle blocks 1 2 0 can be fixed. In other words, the pitch fixing hook frame 141 serves as a spacing fixing member. Therefore, when the size of the semiconductor device to be tested is changed and thus the carrier is replaced, the equally spaced fixed hook frame ι 41 can be replaced, each of which has a width which corresponds to the configuration - is mounted The distance between the clamping devices on the replaced carrier board is in pairs. Therefore, the opener ioo according to the present invention does not need to be replaced because the pair of foot pins 120 can be adjusted in accordance with the spacing therebetween.

Cj As shown in Fig. 2, the four springs 1 42 made of elastic material are attached to the individual ends of the two guide bars 13 〇. The four springs 1 42 can resiliently urge the equally spaced block 120 into a spacer hook 141 positioned between the pin blocks 120. The springs 142 apply their elastic forces to form a pair of the needle blocks 120, so that the needle blocks 120 are positioned in the blocks to receive the compartments, and are fixed by the spacing The width W of the hook frame 1 41 is spaced apart from each other. As described above, the size of the semiconductor device to be tested is changed to '10 200913110 and thus the current carrier is replaced with another carrier, so that the clamping device is used. In terms of the distance between them, the constituent-paired holding device is different from the current carrier, and the opener 100 according to the present invention is adapted to replace the current spacing fixing hook 141 with The other spacing fixes the hook frame (4)' and the spacing corresponds to the distance of the clamping device within the replaced carrier. Therefore, it is possible to apply to the replacement carrier without replacing the opener according to the present invention. ^ Γ <Application Example 1 of Specific Embodiment 1> The specific embodiment 1 is implemented in such a manner as to contain the springs 142 for the elastic member to be used as a spacer member. In the first example, as shown in Fig. 3, the opener 1A contains a plurality of spacer holding hooks M3 instead of springs. The plurality of pitch-holding hook frames 143 are utilized so that the respective pairs of the needle-hand blocks 12 are spaced apart from each other by a pitch corresponding to the width w of the fixed-fishing frame 141, and are fixed to the foot block Accept the compartment. Therefore, although the current carrier is replaced with another carrier, the opener 100A only needs to replace the equally spaced hook frame 41 and the spacer retaining hook frame 143 without replacing itself. That is, the opener i 00A can be applied to the replaced carrier plate. It can be noted that the pitch fixed fishing frame and the pitch maintaining hook frame are constructed in an integrated manner. <Application Example 2 of Concrete Embodiment 1 The embodiment of the application example 1 of the present embodiment is a method of movably connecting a pair of pin blocks 120 to the opening tablet. and

200913110 In this application example 2, as shown in FIG. 4, the implementation method is to form a pair of pin segments, such as a pin block 12〇b, to integrally construct the plate 110. And the other foot block l2〇a is supported and movably connected to the opening plate 11〇. That is, as described in the application example 2, the pitch is a position determining device, and the one decides to be at another position of 120a. Paired from the Ai Yi pair by a pair of open foot pins to simultaneously explain that the specific embodiment converts the gripping device into a chatter to release the gripping state (4), preferably setting a position In order to be able to release the mounted clamped state during the replacement. The opening and closing of the 120a and 120b of the opener 100B is elastically supported by the opening spring 1 4 2 to hold the device in a state of being held by the holding device of the side pin block-carrier. Will be able to listen to the changes with a single turn-on. In this case, the foot block is moved to the holding device in pairs

Figure 5 is a partial exploded view - the second embodiment of the opener 圏 ' which illustrates a 坌 hook year Chu (9) figure opener 5 (J East. Figure 6B system., a solid side view, The slanting distance of the fishing frame 54 is specifically implemented. The 142 example 1 is implemented as a method for accommodating the spacing between the first and second embodiments according to the present invention. The spacing is fixed from the fixed hook frame 1 4 1 and the device viewed from the direction A. That is, as shown in Fig. 5 to 12 200913110

And the solid fixed fishing frame 541 of the embodiment 2 of the present invention has a plurality of spacings 542' at the ends of the two ends, and constitutes a pair of pairs of needle blocks 52〇. The plurality of protrusions are received by the recess 521 to receive the equally spaced retaining projections 542. In the second embodiment, the hook frame 542 is fixed by the spacing of the retaining projections 542. The arrangement as a spacer member is used to be fixed as a pitch similar to the specific embodiments 1 and 2. The specific embodiment 2 has an application that will be apparent in the specific embodiment 530. It is not necessary to use such guidance in 2. In the foregoing embodiment, the opener is located below the carrier. It should be understood that the specific embodiments may be modified in such a manner that the opener is located at the side of the carrier, wherein the opener constitutes an opening foot on the lower side thereof. Buffer Station Application> When the semi-guided vessel is changed in size, the size of the semi-guided vessel must be changed in size when it is installed in the buffering station of a loading section. A buffer station is provided for a pick and place device to align the semiconductor devices picked up from a customer tray before the pick and place device places the picked semiconductor device on the carrier. The buffer can be provided with a plurality of placement compartments, and the number of the buffers is larger than that of the semiconductor device picked up by the pick-and-place arrangement and the pre-installation device 13 200913110. This is because the semiconductor devices picked up by the pick-and-place device are temporarily placed on the placement compartments (or the first placement compartment), and the compartments are constructed in the placement At the side of the compartment (or the second compartment). In general, when a problem (fault) occurs at a contact socket of a test machine, the pick-and-place device does not place the semiconductor device in a position corresponding to the fault (problem) contact socket. Conversely, the pick and place device will temporarily implant the semiconductor device placed on the fault contact socket on the second placement compartment. Similar to the carrier, when the semiconductor device is changed in size, the S front buffer table must be replaced with the other. However, this can result in increased replacement costs and wasted resources. Therefore, when the buffer station employs the technique adapted to the opener according to the present invention, replacement cost and waste of resources can be reduced. Fig. 7 is a plan view showing a buffer table 700' to which the technique according to the present invention is applied, and a part thereof is disassembled from the buffer table 700. That is, as shown in Fig. 7, the buffer table 700 includes a placement table 710 and a placement area defining a hook frame 720. The placement table 710 is constructed with a plurality of placement compartments 711 for receiving semiconductor devices. Each of the placement compartments 711 has a placement area defined by the four inclined planes 711a, 711b, 712a, and 712b. Two adjacent inclined planes 711a and 711b are integrally formed on the placement table 710. The other two adjacent inclined planes 712a and 712b and the bottom plane 722 are formed in the placement area defining the hook frame 72A. Will be able to understand 14

200913110 This embodiment can be modified in such a manner that the bottom plane is formed within the placement table 710. When the placement area defines that the hook frame 702 is replaced with a hook frame, the placement area is thus changed. In more detail, when the conductor device is changed in size, the current placement area hook frame 720 must be replaced with another placement area definition hook frame, thereby changing the size of the semiconductor device to the modified semiconductor device size. Since the placement area can be adjusted without replacing the current buffer 700, the buffer stage 700 does not need to be replaced. Figures 8A through 8C are plan views illustrating a number of exemplary embodiments in which the hook frames 720, 720a and the system are individually placed within the placement table by standardized placement areas. In the present embodiment, the hook frame 720 is defined in the placement area as two inclined planes 721a and 721b. It will be apparent that this embodiment can be constructed in such a manner that only a single inclined plane is formed within the hook frame 720 defined in the region. Moreover, the manner in which the present embodiment is implemented is to replace the placement hook frame 720. It will be understood that, as shown in FIG. 9, this specific example can be implemented such that the placement area defines the hook frame 920 to move in a diagonal direction (ie, the direction of the arrow a), and contains one for The play field definition hook frame 920 is fixed to the stationary device at the moving position. The fixture in the buffer table of Fig. 9 includes a pusher assembly 94 1 spring 942 and a spacer fixed hook frame 943. The pusher assembly 94 1 elastically supports the placement area definition 92 0 . The springs 942 define the direction of the hook frame 920 in the placement area to modify the other half fields. Also rushing Taiwan Scope 720b internal structure placement modification domain implementation direction installation area installation, bomb hook frame upper 15 200913110 - elastic force applied to the push (four) 941. The spacer fixing hook 943 can be operated. The placement area hook 92G cannot be pushed by the pushing unit 941 at a certain distance, and thus the fixing-placement area. A μ-figure is a conceptual plan view 1 illustrating a buffer station 1 000 according to another application example of the present invention, and a portion of the buffer station 1 being decomposed. That is, as shown in Fig. 10, the two inclined planes 1〇11& and l〇ub are located at the front side and the rear side portion which are placed from 1010 and face each other. The two inclined planes i i i a and 1 〇 i i b are elastically supported by the springs i (4) so that the inclined planes are movable in the front and rear directions. The placement area defines the inclined planes 1 〇 213 and 102 lb which face each other in the right and left directions. Therefore, when the placement area defining hook 1020 is replaced with another one, the placement area can be adjusted. Here, the front side and the rear side means the direction perpendicular to the right side and the left side direction. That is, as described above, the opener according to the present invention can adjust the spacing between the opening pins when the size of each of the semiconductor devices is changed. Therefore, it is not necessary to replace the opener regardless of whether the size of the semiconductor device is changed, thereby reducing resource waste and replacement cost. When the concept of the present invention is applied to a buffer station, the buffer station can adjust the placement area according to the dimensions of the replaced semiconductor device, thus reducing resource waste and replacement cost. While the invention has been described in detail with reference to the exemplary embodiments of the embodiments of the invention It is within the spirit and scope of the exemplary embodiments of the invention as defined in the scope of the invention.
